Application Server
Advanced Settings

The Application Server
Advanced settings allow you to set general properties for deploying applications.
These properties enable you to ensure and monitor that changes to deployed
applications are detected and the modified classes reloaded.

Setting Applications Configurations

If dynamic reloading is enabled, the server periodically checks for
changes in the files of the deployed application and automatically reloads
the application with the changes. Dynamic reloading is useful in a development
environment because it allows code changes to be tested quickly. In a production
environment, however, dynamic reloading may degrade performance.

To configure dynamic reloading from the Applications Configuration page,
configure the following:

Reload: Enable or disable dynamic reloading with the Enabled
checkbox.

Reload Poll Interval: Specify how often the server checks
for changes in the deployed applications.

Admin Session Timeout: Specify the amount of time before the
Admin Session times out and you have to log in again.

To configure auto deploy settings

The auto deploy feature enables you to deploy a prepackaged application
or module by copying it to the domain-dir/autodeploy directory.

For example, copy a file named hello.war to the domain-dir/autodeploy directory. To undeploy the application, remove the hello.war file from the autodeploy directory.

Go to the Applications Configuration page.

Enable or disable auto deploy by selecting or deselecting the
Enabled checkbox.

In the Auto Deploy Poll Interval field, specify how often the
server checks the auto deploy directory for application or module files.

Changing the poll interval does not affect the amount of time it takes
to deploy an application or module.

In the Auto Deploy directory, if you specify the directory where
you build your application, then you won’t have to copy the file to
the default auto deploy directory.

The default
is a directory called domain-dir/autodeploy.

To run the verifier before deployment, select the Verifier Enabled
checkbox.

The verifier examines the structure and content of the
file. Verification of large applications is often time-consuming.

To precompile JSP pages, select the JSPs checkbox.

If
you do not select this checkbox, the JSP pages are compiled at runtime when
they are first accessed. Because compilation is often time-consuming, in a
production environment select this checkbox.

Click the Add Property button to specify additional settings.
